A cousin, who lives in South Dakota, sent me some information she found concerning my 3rd great grandfather. She’s been helping trying to locate his grave in SD. While she didn’t have any further information on that, she did find this article about him in the Grant County (South Dakota) review dated March 10th, 1892:
(Lorenz Heller), an old man over 70 years of age, residing four miles north of Revillo, was rolled and trampled by an infuriated bull on Monday afternoon, and died from the effects of the injuries the same night. The animal was de-horned and the old man was endeavoring to drive it into the stable with a pitchfork when it turned upon him.
Lorenz was born in Prussia in 1817. He arrived with his family at Castle Garden in New York City on May 16, 1866. They settled in Wisconsin and then went to South Dakota in about 1881.
